树形图鼠标悬停在打开的弹出窗口并显示内容 [英] Tree view mouse over open a pop window and show the contents

问题描述

我使用asp树视图.我已经绑​​定了数据集的树视图.我想在鼠标悬停时在弹出窗口中显示树视图的内容.我对数据集中的每个节点都有一些描述，如何在鼠标弹出时显示它们结束.

这是我的代码:

Hi,

iam using asp tree view .i have binded tree view from a dataset .I want to show a content of tree view in pop up in mouse over.I have some description for each node in the dataset how to show them in a pop in mouse over.

here is my code:

TVContent.Nodes.Clear();
            DataTable topics = dsSOW.Tables["Tableofcontents$"];
            drText = dsSOW.Tables["Tableofcontents" + "$"].Select("Mappingcode is NULL");

            if (drText.Length > 0)
            {
                foreach (DataRow drItem in drText)
                {
                    string ss = drItem.ItemArray[1].ToString();

                    string ss1 = drItem.ItemArray[0].ToString();
                    if (ss1 != string.Empty)
                    {
                        TreeNode node = new TreeNode(ss, ss1);
                          node.PopulateOnDemand = false;
                        TVContent.Nodes.Add(node);
                        
                        PopulateNode(node);

                    }

 

                }
            }

 


        protected void PopulateNode(TreeNode node1)
        {
            decimal order = Convert.ToDecimal(node1.Value);
            drText = dsSOW.Tables["Tableofcontents" + "$"].Select("Mappingcode=''" + order + "''");

            if (drText.Length > 0)
            {
                foreach (DataRow drItem in drText)
                {

                    string ss = drItem.ItemArray[1].ToString();

                    string ss1 = drItem.ItemArray[0].ToString();


                    TreeNode node = new TreeNode(ss, ss1);
                  
                    node1.ChildNodes.Add(node);
                     snode = node.Value;
                    if (snode != string.Empty)
                    {

                        drText = dsSOW.Tables["Tableofcontents$"].Select("Mappingcode=''" + snode + "''");
                        if (drText.Length > 0)
                        {
                            PopulateNode(node);
                        }
                    }
                }


            }

            TVContent.Attributes.Add("OnClick", "OnTreeClick(event)");
        }

请帮忙. ！
